WHEEL-PLOW.

SPECIFICATION forming part of Letters Patent N o. 735,096, dated August 4, 1903.

Application filed February 7,1903. Serial No. 142,372- (NO model-l To all whom it may concern."

Be it known that I, EDGAR M. HIOKMAN, a citizen of the United States, residing at Chattanooga, in the county of Hamilton and State of Tennessee, have invented a new and useful Improvement in vWheel-Flows, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to wheel-plows,/and

io particularly to means for securing the rear caster-wheel of a Wheel-plow to the beam or frame. Said means of securing the rear caster-wheel includes means for elfecting a vertical adjustment between said wheel and the I5 beam or frame of the plow.

In the accompanying drawings, Figure l is a plan showing the rear caster-wheel connected to the rear end of the plow-beam. Fig. 2 shows Fig. l turned over toward the zo left, so as to expose the side which is toward the right in Fig. l, the wheel and a portion of the wheel-axle bearing being removed. Fig. 3 is an axial sectional view through the wheel and the bearing which supports the wheel-axle. Fig. 4 is an elevation of the adjacent end of Fig. 3. Fig. 5 is an elevation of the adjacent end of Fig. 3 after the wheel has been removed. Fig. 6 isa rear elevation of an arm by which the direction of the cas- 3o ter-wheel is controlled.

Referring to said drawings, l is the rear portion of the plow-beam or a portion of the plow-frame. A hinge-plate 2 is shown secured to the side of the rearend of said beam by means of bolts la. Said plate has a transverse aperture 22 to receive a cylindric shaft 2b.l A U-shaped yoke 3 has the ends of its arms 3 provided with apertures 3b, and said ends extend over the plate 2, so as to bring 4o the apertures 3b into line with the aperture 2Ct and receive the ends of the shaft 2" into the apertures 3". Thus the yoke 3 is hinged to the plow-beam, so as to turn laterally upon the shaft 2b. Said yoke supports a hub or bearing 4, and said yoke and ysaid hub may be joined in any suitable manner, preferably by casting them as an integral piece.

The axle 5 has a head 6, which is cylindric in form and of proper dimensions to fill the 5o interior of the hub et; but the axis of said hub and the axis of said axle do not coincide.

Said head is eccentric to the axis of the axle to such an extent as to make possible the ielative raising and lowering of said hub and said axle by turning said head in said hub. Figs. 3, 4, and 5 of the drawings show said axle in the lowermost position, and the dot.- ted circle in Fig. `5 shows the uppermost position for the axle. i

The head 6 may be secured in the hub in 6o any suitable manner. The drawings showa collar 6 surrounding said head at the juncv tion of the latter and thevaxle and extending over the end of the hub which is adjacent to the axle. This prevents the movement of the head toward the left, as shown in Fig. 3. The drawings further show a circular plate 7 extending over the opposite end of the head and said hub and secured to said head by means of two screw-bolts 7a. Said plate 7o prevents the movement of said head toward the right, as seen in Fig. 3. Said head may be made a trifle shorter than said hub, so that the tightening of said bolts will bind said collar 6a and the outer edge of said plate 75 7 against the ends of said hub, and thus prevent the rotation of said head after it has been rotated into the proper position to bring the axle 5 to the desired elevation. The drawings aiso show a set-bolt 8 extend- 8o ing through the wall of the hub '4 and bearing against the adjacent face of thehead 6, so as to prevent the rotation of the latter. It will be understood that either of these means can be used separately 'for the purpose of 85 binding the head 6 non-rotatably in vsaid hub. The drawings also show said hub 4 set obliquely to the plane of the yoke 3, the righthand end of said'yoke being directed downward and forward. This causes the axle 5 to 9o extend downward and forward, so that the upper portion of the caster-wheel lO will lean forward and away from the verticalplane extending through said beam and yoke,where by said wheel is given the Well-known position adapting it to bear against the land side of the furrow.

The upper arm of the yoke 3 may have the lateral stub or extension 3 for receiving an arm 9, which rises obliquely from said stub roo toward the right and terminates above said wheel. -Any suitable connection may extend from the upper end of said arm to some other portion of the plow for controlling the movement of the Wheel 10, hub 4, and yoke 3 upon the hinge formed by the shaft 2b. Said Wheel may, however, be allowed to trail according to the movement of the beam l.

It is obvious that the plate 2 may be omitted and the yoke 3 hinged directly to the beam. It is also obvious that the yoke 3 may be provided with but one arm. Said yoke is an oscillatory member hinged to the rear end of the plow-frame on a vertical axis, and said member comprises a hub or bearing adapted to receive the eccentric head on the axle 5.

I claim as my inventionl. In a Wheel-plow, the combination with the beam or frame, of an oscillatory member hinged to the rear end of said frame on a ver- Vtical axis, said member having a transverse hub, an axle having an eccentric head extending into and secured within said hub, and a Wheel secured upon said axle.

2. In a wheel-plow, the combination with the beam or frame, of an oscillatory member hinged to the rear end of said frame on a vertical axis, said member having an oblique transverse hub, an axle having an eccentric head extending into and secured Within said hub, and a wheel secured upon said axle.

3. In a Wheel-plow, the combination with the beam or frame, of an oscillatory member hinged to the rear end of said frame on a vertical axis, said member having a transverse cylindric hub, an axle having `an eccentric cylindric head extending into and secured Within said hub, and a Wheel secured upon said axle.

4. In a wheel-plow, the combination with the beamor frame, of an oscillatory member hinged to the rear end of said frame ou a vertical axis, said member having an oblique, transverse cylindric hub, an axle having an eccentric, cylindric head extending into and secured Within said hub, and a wheel secured upon said axle.

5. In a Wheel-plow,V the combination with the beam or frame, of an oscillatory member hinged to the rear end of said frame upon a vertical axis, said member having a transverse hub, an axle having an eccentric head extending into said hub and having a collar at the junctionY with said axle, and a plate, 7, extending over the end of said hub and head and secured to the latter.

6. In a wheel-plow, the combination with the beam or frame, of an oscillatory member hinged to the rear end of said frame upon a vertical axis, said member having an oblique, transverse hub, an axle having an eccentric head extending into said hub and having a collar at the junction with said axle, and a plate, 7, extending over the end of said hub and head and secured to the latter.

7. In a Wheel-plow, the combination with verse, cylindric hub, an axle having an eccentric, cylindric head extending into said hub and having a collar at the junction with said axle and a plate, 7, extending over the end of said hub and head and secured to the latter.

9. In a Wheel-plow, the combination with the beam or frame, of an oscillatory member hinged to the rear end of said frame upon a vertical axis, said member having a transverse hub, an axle having an eccentric head extending into said hub and having a collar at the junction with said axle, a plate, 7, extending over the end of said hub and head and secured to the latter, and a set-bolt extending through said hub against said head.

lO. In a wheel-plow, the combination With the beam o r frame, of a hinge-plate, 2, having a vertical aperture, a yoke having arms provided with apertures in line with `the aperture in said plate, ashaft extending through said apertures, and said yoke embodying a transverse hub, an axle, 5, having an eccentric head extending into said hub, and a wheel on said axle.

ll. In a wheel-plow, the combination With the beam or frame, of a hinge-plate, 2, having a vertical aperture, a yoke having arms provided with apertures inline with the aperture in said plate, a shaft extending through said apertures, and said yoke embodying a transverse oblique hub, an axle, 5, having an eccentric head extending into said hub, and a Wheel on said axle.

l2.

In testimony whereof I have signed my name, in presence of two witnesses, this 24th day of January, in the year 1903.
